Flexor Tendon Injuries

When these tendons are injured, movement can be limited or completely lost, making early diagnosis and treatment critical.

What Are Flexor Tendons?

Flexor tendons are cord-like structures that connect muscles in the forearm to the bones in your fingers and thumb. When the muscles contract, they pull on the tendons, allowing your fingers to bend and make a fist. Flexor tendons run from your forearm, through the wrist and hand, all the way to the fingertips.

What Causes Flexor Tendon Injuries?

Flexor tendon injuries usually occur due to trauma or repetitive strain. Common causes include:

• Sports-related injuries: Football, wrestling, rugby or other contact sports
• Deep cuts or lacerations: From knives, glass or power tools
• Health conditions: Rheumatoid arthritis or chronic tendon wear

Even small lacerations can significantly affect tendon function if they occur in critical areas of the hand. Tendons can also rupture without a cut, either from wear, forceful pulling or tendon-muscle separation.

What are Flexor Tendon Injury Symptoms?

You may have a flexor tendon injury if you notice:

• An open injury such as a cut
• Inability to bend one or more joints of your finger or thumb
• Pain when bending the finger
• Tenderness along the finger on the palm side of your hand
• Numbness or tingling in the fingertip

In injuries caused by laceration, additional symptoms may include significant bleeding and nerve involvement, leading to numbness or tingling in the hand.

How are Flexor Tendon Injuries Treated?

Nonsurgical Treatment

• Splints: May be used temporarily to protect the finger or hand
• Minor injuries without complete tendon rupture may sometimes heal with careful immobilization and monitoring

Surgical Treatment

• Most flexor tendon injuries, especially cuts or complete ruptures, require surgery to reattach the tendon
• Surgery often includes repair of associated structures, such as nerves or blood vessels
• Postoperative splinting and hand therapy are critical to protect the tendon and restore movement

What is Flexor Tendon Injury Recovery Like?

Recovery from a flexor tendon injury can take months and requires commitment to hand therapy.

• Hand therapy: Exercises and guided movement are important to regain strength, flexibility and function
• Risks: Scarring and stiffness are common; additional surgery may sometimes be needed to improve motion
• Outcomes: Many patients regain good function after repair, though recovery varies depending on injury severity, timing of treatment and adherence to therapy

Flexor tendon injuries do not heal on their own, and early intervention greatly improves the likelihood of regaining full hand function. If you suspect a tendon injury, seek medical attention promptly.
